PLATFORM-DOOR Foa CARS.

SPECIFICATION forming part of Letters Patent No. 395,324, dated January1, 1889.4 Applatill filed February 23, 1888. Serial No. 265,029. (Nomodel.)

To aZZ whom, it may concern.-

Be it known that I, JACOB HAIsH, a citizen of the United States,residing' at De Kalb, in the county of De Kalb and State of Illinois,have invented certain new and useful Improvements in Platform-Doors forRailway- Coaches and I do hereby declare the following' to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being' had to the accompanying' drawings, and to lettersor 'figures of reference mal'ked thereon, which form a part of thisspecification.

My invention has reference to certain improvements in platform-doors forrailwaycoaches, and pertains more particularly to special mechanism forcarrying' the door to .and from the platform, and coincidently raising`the lid or trap-door which covers the interval in the platform occupiedby the side steps thereof.

It is the design of my invention to place a sliding' door connectedwit-h the trap or lid aforesaid at each side of each end oftherailway-coach. lherc would therefore be four of the devices shown Vinthe drawings attached to each railway-coach; but inasmuch as each isidentical with the other I do not deem it necessary to show or describethe construction and operation of more than one of said devices. It is'the intention also that the sliding' door, when projected to the end ofits ontthrow, will be coteri'ninous lwith the projecting' roof of thecoach and the outer verge of the platform, so that when said door is metby the adjacent sliding' door upon the adjoining' coach the combi nedett'ect ofthe two doors will be to completely close the interval betweenthc adjacent ends of the two coaches and thereby render transit from onecoach to the other safe and comfortable, and also to exclude from theentrance within the coach, in case the doors of the latter should beopen, all storm, and cinders from the locomotive, or dust occasioned bythe passage of the train.

In the drawings, Figure l. is a side elevation of the end of4 arailway-coach provided with my invention, and a portion of the sliding'door ofthe adjacent coach. Fig'. 2 is a detail perspective view, and lig'. Si is a detail section of the securing-bolt.

A is au ordinary railway-coach, with the proj eeting' platform I3 andhood F.

C is an external stanchion attached vertically to the outside of thecoach at about the width of the sliding' door from the end of the coach.

I) is a sliding' door suspended and hinged to the stanehion C by meansof the diagonal pivoted braces H and J'.

As shown in Fig'. l, the brace H is pivoted at iis lower end to the clipIl', attached near the lower extremity of the stanchion C, and isextended from its pivotal point aforesaid diagonally upward to the rearof the door D. On the rear or inner edge ofthe door D is suitablyattached a vertical ly-slotted bracket, E. The upper end of the brace His bent inward at rig'ht angles, and the bent portion projected withinand fitted to traverse the slot E in the side movement of the door I),or the upper end of the brace Il may be furnished Vwith a bolt-holefitted to receive a bolt, which can be passed through said braceperpendicular thereto an d set loosely in said slot E.

The diagonal brace J is suitably pivoted at or near the lower innercorner of the door D, and projected diagonally upward and across thebrace 1I, and seated, substantially as has been described in referenceto the upper end ofthe brace Il, in the vertically-slotted bracket Kattached to the stanchion C.

rlhe relative positions of the braces H and eI are such that when thedoor D at the limit of its euttlnfow they cross each other atsubstantially rig-ht angles, and when said door is thrown inward, toopen the passage to the platform B, said braces are each substantiallyvertical. As the door D is moved inward-that is, alongside ot' the coachA, from the position shown in Fig'. I -the upper ends of the braces Iland .I traverse upward the .slots E and K, and thus accommodatethemselves to the change of space between the door I) and the stauchion(i. IVhen the door D passes from this position to the outward, (shown inFig'. 1,) the upper ends of the braces II and .I descend, respectively,in the slots E and K, and thus are enabled to extend across theincreased space between the stanchion C and door I).

It is the intention to support and carry IOO substantially all of theweight of the door D upon the braces H and J, and the latter are made ofsufficient strength and seated sufficiently strong' to accomplish thispurpose. In this sliding movement the upper edge of the door D is heldwithin and traverses a horizontal groove or inverted trough, L, formedin the lower edge of the roof F.

G is a rock-shaft seated transversely of the coach A, at or near theinner edge of the platform B, and to the shaft G is rigidly attached thelid or trap-door M, the function of which is to open and close theopening at the side of the platform B occupied by the steps N.

The shaft G is in length equal to the width of the lid M, or should atleast be sufiiciently long to rigidly and certainly control said lid. Onthe external end of the shaft G is rigidly seated the pinion O, directlybeneath and in line with the lower edge of the door D. To the bottom ofthe door D, and in proper relation to the pinion O, is affixed the rackP, adapted to engage and partiallyT rotate said pinion in certainportions of the sliding movements of said door. The rack P is locatednear the inner side of the door D, although its precise location iscomparatively unimportant. It is essential, however, that the rack P beof sufficient length to engage and rotate the pinion O, and thereby theshaft G, sufficiently to change the lid M from a vertical to ahorizontal position, and reversely, as the case may be. After the rack Phas sufficiently rotated the pinion O, as aforesaid, the residue of thedoorD, beyond the end of said rack, is carried over said pinion withoutin any Way affecting the latter.

The contiguous edges of the door D are held in proper relation and fromwithdrawal by any suitable devices.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is-

l. The combination of the coach A, provided on its side with thevertical and external stanchion, C, and the slotted bracket K, attachedthereto, the Way or groove L on the lower edge of the roof, the door D,sliding on said way or groove and provided with the slotted bracket Eand the rack P, the shaft G and pinion O engaging said rack andoperating the door, and the lid M, attached to the shaft G, allsubstantially as Vand for the purposes set forth.

2. The combination of the coach A, having a way or trough, L, along itsroof and an eX- ternal vertical stanchion, C, having the slotted bracketK attached thereto, the door sliding in said way or trough and upon therack P, and the braces H and J, pivoted at one end, and at the othersliding in the slots of said bracket.

3. In combination with the car, the door D, sliding in the way or troughL at its upper end, and at its lower end on the rack P, with the lid M,and the pinion O and shaft G, to which shaft said lid and pinion areiiXed.

4. In a car, the lid M, combined with and fixed to the shaft G, whichcarries the pinion.

by which the door is moved, and with the door, substantially asdescribed.

5. In a car, the combination of the sliding side door with a lid tocover the steps, substantially in the manner set forth, whereby theforward or backward movement of the door serves, respectively, to loweror raise said lid, substantially as set forth.

G. In a railroad-car having movable side.

doors, a lid for covering the steps when the side doors are movedforward operated simultaneously with the movements of said side doors.

In testimony whereof I affix my signature in presence of two witnesses.

JACOB HAISH.
